:to add them ... click edit above.
:bracket your report with <nowiki><pre> and </pre></nowiki> and it should show up in a blue box:
like this
:click on '''preview''' to see it is as you wish it to appear ...
:and if so, click on '''save page'''

==Overflow in rob(n).mem(refvelup)==

:'''runtime error 6. overflow.
:[[Senses]] Modual
:[[Senses#Public_Sub_lookoccurr|Public Sub lookoccurr]] routine

:The following line gives runtime error 6, Overflow often.
:The problem being the ^2 produces a value greater than 32000 for those variables.

rob(n).mem(refvelscalar) = Sqr(rob(n).mem(refvelup) ^ 2 + rob(n).mem(refveldx) ^ 2)
' how fast is this robot moving compared to me?

:Puroposed fix uses Long integers for rob(n).mem(refvelup) and rob(n).mem(refveldx :
rob(n).mem(refvelscalar) = CInt((CLng(rob(n).mem(refvelup)) ^ 2 + CLng(rob(n).mem(refveldx)) ^2 )^0.5)

see [[Senses]] page for complete code and error in context.

==Overflow in rob(o).vx==

see [[Senses]] page for complete code and error in context.

:runtime error 6 Overflow
:[[Senses]] modual
:[[Senses#Public Sub lookoccurr|Public Sub lookoccurr]]

<pre>
rob(n).mem(refveldx) = (rob(o).vy * Cos(rob(n).aim) + rob(o).vx * Sin(rob(n).aim)) - rob(n).mem(veldx)

hover values:
n = 28 refveldx = 697 rob(n).mem(refveldx)= -31 o = 6
rob(o).vy = 2107.767 rob(n).aim = 1.415345
rob(o).vx = 93156.06 rob(n).mem(veldx) = 31
</pre>
where rob(o).vx overflows.

:PY thinks this may be it. He says:
:The bots discovered a loophole. I have plugged it and am waiting to see if it finds another one.
:The modification is right at the top of "updpos" in the "physics" module.
:I changed

With rob(t)
 If t <> moving and not .fixed Then
Maxspeed = 30 / (.mass / 2) 'Set maximum speed. Absolute max = 60

to

With rob(t)
 If t <> moving Then
Maxspeed = 30 / (.mass / 2) 'Set maximum speed. Absolute max = 60

:This line of code was deliberately preventing fixed robots from having the velocity limits applied to them.
:After all they aren't moving so why would they need it.
:No more loophole now.

===Velocity/Acceleration error===
:This in the [[Robots]] modual, [[Robots#Public_Sub_updatepos|Public Sub updatepos]] routine.
:Replace:
If .mem(216) <> 0 Then
.Fixed = True
.vx = 0
.vy = 0
Else
.Fixed = False
End If

With:

If .mem(216) <> 0 Then
.Fixed = True
Else
.Fixed = False
End If
if .Fixed then
.vx = 0
.vy = 0
.ax = 0
.ay = 0
End If


:Since ths fix, PY also discovered the following ...
:which we think is at the very source of and contributing to all of the above bugs.

====Final Velocity fix ???====

The new code/fix:
<pre>
Maxspeed = 30 / (rob(t).mass / 2)
totv = Sqr(rob(t).vx ^ 2 + rob(t).vy ^ 2)
If totv > Maxspeed Then 'top speed limit routine 2 changed faster speeds for lower mass robots
maxcel = totv / Maxspeed
rob(t).vx = rob(t).vx / maxcel
rob(t).vy = rob(t).vy / maxcel
End If
Maxspeed = 30 / (rob(k).mass / 2)
totv = Sqr(rob(k).vx ^ 2 + rob(k).vy ^ 2)
If totv > Maxspeed Then 'top speed limit routine 2 changed faster speeds for lower mass robots
maxcel = totv / Maxspeed
rob(k).vx = rob(k).vx / maxcel
rob(k).vy = rob(k).vy / maxcel
End If
</pre>
:See [[Physics]] modual [[Physics#Private_Sub_repel|Repel]] subroutine for where it goes in context.
:This fix seems to have worked ... I haven't had a runtime error since. {{User:Griz/sig}}

==Abs(.mem(aimsx)) error==
:see [[Robots]] for complete code and error in context.
:In [[Robots]] modual ...
:[[Robots#Private Sub updvars2|Private Sub updvars]]:

:bug ... Abs brackets incorrect.
:change:
If Abs(.mem(aimsx) > 1256) Then .mem(aimsx) = 1256 * Sgn(.mem(aimsx)) 'new crash fix?
If Abs(.mem(aimdx) > 1256) Then .mem(aimdx) = 1256 * Sgn(.mem(aimdx))
:to
If Abs(.mem(aimsx)) > 1256 Then .mem(aimsx) = 1256 * Sgn(.mem(aimsx)) 'new crash fix?
If Abs(.mem(aimdx)) > 1256 Then .mem(aimdx) = 1256 * Sgn(.mem(aimdx))

==Overflow due to Zero length DNA==
:[[Mutations]] modual
:[[Mutations#Public Function NextElement|Public Function NextElement]]

<pre>
Public Function NextElement(ByRef DNA() As block, beginning As Integer, tipo As Integer, value As Integer)

As Integer
'takes the input for the first value in a gene and returns the position of the next statement
'as defined by tipo and value
Dim k As Integer
Dim uboundarray As Long

uboundarray = UBound(DNA())
If DNA(uboundarray).tipo <> 4 And DNA(uboundarray).value <> 4 Then
ReDim Preserve DNA(uboundarray + 1)
DNA(uboundarray + 1).tipo = 4
DNA(uboundarray + 1).value = 4
End If
k = beginning
</pre>
change:
If beginning > 0 Then ... To:
If beginning > 0 And beginning < uboundarray Then
to fix the overflow problem caused when a robot has zero DNA length.
<pre>
While Not (DNA(k).tipo = 4 And DNA(k).value = 4) And Not (DNA(k).tipo = tipo And DNA(k).value =

value)
k = k + 1
Wend
If Not (DNA(k).tipo = tipo And DNA(k).value = value) Then k = -1
Else 'beginning wasn't valid
k = -1
End If

NextElement = k
End Function
</pre>

==New Simulation error after altering Mutations==

'''NOTE: ... also a fix for version 2.4.6'''

The bug:
:Go into the GUI in a running sim and moving the mutations slider off center (any value)
:Click change to return to the simulation. Should run happily
:Go back to the GUI options menu and the program will crash with a "type mismatch" error
:Mutlab.Caption has to a text value.

:[[Optionsform|Optionsform(code)]] modual
:[[Optionsform#Private_Sub_DispSettings|DispSettings]] routine
:for full code and error in context.

:In this IF loop, make this replacement: (replace the Red with the Blue)
If TmpOpts.MutCurrMult > 1 Then
'MutLab.Caption = (TmpOpts.MutCurrMult) + " X"
 MutLab.Caption = CStr(TmpOpts.MutCurrMult) + " X"
Else
MutLab.Caption = "1/" + Str(2 ^ -MutSlide.value) + " X"
End If
